FUEL-BURNING APPARATUS.

Application filed November 20, 1924.

This invention relates to improvements in apparatus for burning liquid fuel or the like, and has for its object to provide a drain and safety cut-out system which may be readily attached to and removed. from the balance of the apparatus. Another object consists in the provision of a new and improved safety cut-out device.

These and other objects are more fully described in the following specification and shown in the accompanying drawings, in which Fig. 1 is a side elevation of apparatus e1nbodying my invention.

Fig. 2 is a vertical section through one end of such apparatus.

Fig. 3 is an inverted plan or bottom view of the apparatus shown in Fig. 1.

Fig. '-l is a plan view of the collecting cups and drain pipes.

Fig. 5 is a perspective of the locking means.

Fig. 6 is a vertical transverse section along the line 66 of Fig. 1.

Fig. 7 is a similar view along the line 7'(' of Fig. 1.

Fig. 8 is a similar view along line 8-S of Fig. 1.

F 9 is avertical section drawn to an enlarged scale along the line 99 of Fig. 8.

Fig. 10 is a side elevation of the cut-out switch and bucket showing the switch in position opening the motor circuit.

F 11 is an inverted plan view of the switch and actuating member, the latter being pivoted out of operative position.

Fi 12 is a perspective of the switch actuating bucket and arm.

Like numerals refer to like elements throughout the drawings, in which 10 desighates generally the main casing containing certain functioning units of a liquid fuel burning apparatus, and serving as a conduit for air supplied from the motor blower 11 to the combustion chamber or firepot 12 which is supported upon the brick or masonry foundation 13. Adjustable pedestals 1 1 at the opposite end of the casing assist in the sup-v port of the apparatus. Leading from the firepot 12 at the rear end thereof are the drain passages .12. Located therebeneath are the cup or sump members 15, one at each side of the apparatus as shown in Fig. 6, for example. Leading rearwardly from each of the cups 15 is a drain pipe 16, which com- Serial No. 751,006.

mimic-ates with the sealing member 17 shown in detail, for example, in Fig. 9. The member 17 comprises a reservoir 17 an inlet port 17", an outlet port 17, and a third port 17. A partition 1? depends into the reservoir 17 beneath the level of outlet port 17. Between the sealing members 17 extends a cross pipe 19, which is provided with an enlarged cup portion 19 intermediate its extremities, open at the top and in alignment with the drain port 10 at the bottom of casing 10. From one of the sealing members 17 extends the spout 117 normally located over a collecting bucket or receptacle 20, which is suspended by links 21 from a spring arm This spring arm is pivoted to the under side of the casing at 22, and. limited in its morei'nentby the guard strip 23 secured to the under side of the casing. Located in the easing is the switch 2% in circuit with the electrically actuating apparatus and opening the same with the normally spring extended button 245* in extended position, as shown in Fig. 10. When the. arm 22 is in assembled position and the bucket empty, the arm will maintain the button 24 depressed and the circuit closed, as indicated in Fl. 1, for example.

Depending from the underside of casing 10 are the supportin brackets 25, each having the concaved seat or socket portion 25 and the under cut shoulders 25" formed by the tapered grooves 25. The concavity 25 furnishes a seat for the pipe 16, and co-acting with each is a locking wedge member 26. having the concaved seat portion 26 and the tapered shoulders 26". hen the pipes 16 are seated in the sockets 25 the locking members 26 may be driven home into wedged. locking relation with the brackets 25, as will be obvious, thus clamping the drain pipes and the associated elements in proper assembled relation with respect to the casing 10 and combustion chamber 12.

With the apparatus properly assembled. should the ignition means fail,liquid fuel will accumulate in the combustion chamber or iireport 12 until it flows out through passages 12 into the suinps 15, from whence it will he conducted. through pipe 16 into the sealing members 17, from one of which it will flow into thebucket 20 until the weight of the fuel therein is sufiicient to bend the spring arm 22 downwardly to permitopening of the switch 24:, which will discontinue the actuation of the electrical apparatus. Should fuel leak or accumulate in the casing 10. it will flow out through the port It) into the cross pipe It), and likewise be conducted into the bucket 20. By this means should the ignition fail or should the supply pipe leak, the apparatus will be automatical- 1y thrown out of operation, thus obviating further escape of combustible fuel.

is soon small amount of fuel has accumulated in the sealing member 1?, draught air or air for combustion will be prevented from e rapi o through the pipes 16. Should it be dcsii to cut out the electrical apparatus, the arm may be swung laterally to the position shown in Fig. ll, permitting the switch to open.

In order to remove the drain structure described above, it is merely necessary to release the locking members 26 from wedg ing relation with brackets 25, after which the pipes 1(2- and their associated elements may be readily removed for replacement or repair.

It ill be obvious that my invention is susceptible of modification, and I do not wish tobe restricted to the form shown and described, except as defines in the appended claims.

lVhat I claim is:

1. In a fuel burning apparatus, a receptacle, means for collecting unburned fuel and conducting it to said receptacle, a switch having means for normally urging it to open, and a flexible arm from which the receptacle depends, said arm being adapted to yieldably hold said switch closed. except when said receptacle contains a given weight of unburned fuel.

2. In a fuel burning apparatus, a receptacle, means for collecting unburned fuel and conducting it to said receptacle, an adjustable support for said means, a switch having means for normally urging it to open, and a flexible arm from which the receptacle depends, said arm being adapted to yieldably hold said switch closed except when said receptacle contains a given weight of unburned fuel.

3. In a fuel burning apparatus, a receptacle, means for collecting unburned fuel and conducting it to said receptacle, a switch having means for normally urging it to open, and an element from which said receptacle depends, said element being adapted normally to hold said switch closed, to allow said switch to open when said receptacle contains a given weight of unburned fuel, the switch and element being adapted to automatically reset themselves into normal position when the receptacle becomes empty.
